CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application Ser. No. 60/610,115 filed Sep. 15, 2004.

BACKGROUND OF THE INVENTION

Potassium (K⁺) channels are a diverse class of ion channels and have several critical roles in cell function. One role is in neurons, where K⁺ channels are responsible, in part, for determining cell excitability by contributing to membrane repolarization following depolarization, resting membrane potential, and regulation of neurotransmitter release. The M-current, measured by electrophysiology recording methods and by pharmacology, has been described as a dominant conductance in controlling neuronal excitability. Pharmacological activation or suppression of M currents by small molecules could have profound effects in controlling neuronal excitability. Recently, Wang reported that co-assembly of the KCNQ2 and KCNQ3 potassium channels underlies the native M-current in neurons (Wang et al., Science 1998, 282, 1890-1893).

Compounds that block KCNQ channels and M current, including linopirdine and XE-991, demonstrate cognition enhancing effects. The compounds act by increasing the stimulus-evoked release of a number of neurotransmitters in the central nervous system. See Wang et al. Science 1998, 282, 1890; Lamas Eur. J. Neurosci. 1997, 9, 607; Schnee and Brown J. Pharmacol. Exp. Ther. 1998, 286, 709; Zaczek et al. J. Pharmacol Exp. Ther. 1998, 285, 724 and references cited by these papers.

At the time linopirdine and XE-991 were discovered, they were not known to be KCNQ blockers and were not optimized for KCNQ inhibition or selectivity. Thus, potent and selective KCNQ blockers offer a promising opportunity for treating impairments of memory or cognition.

2-Amino-5-carboxamidopyrimidines have been disclosed. See Suto et al. U.S. Pat. No. 5,811,428. Nothing in this reference discloses or suggests the novel compounds of this application.

Biological Methods

The compounds of this invention were evaluated for blocking KCNQ channels using an assay. Representative compounds were confirmed to be KCNQ blockers in a functional assay measuring current through KCNQ channels transfected into oocytes.

Thallium Flux Assay for KCNQ channel blockers. Approximately 20,000 cells/well of an HEK-293 cell line stably transfected with one of the members of the KCNQ family were plated into clear-bottom, black-walled, poly-D-lysine coated, 384 well assay plates in 20 μl/well of low chloride plating medium. Low chloride plating medium was composed of the following: sodium gluconate, 109 mM; potassium gluconate, 5.4 mM; hemi-calcium gluconate, 3.6 mM; magnesium sulfate, 0.8 mM; sodium bicarbonate, 26.2 mM; sodium phosphate monobasic, 1.2 mM; glutamine, 2 mM; glucose, 5 mM; HEPES (pH 7.3) 10 mM, 10×concentration of vitamins (Gibco/LifeTechnologies catalog #11120-052) and 1×concentration of amino acids (Gibco/LifeTechnologies catalog #11130-051).

Following overnight incubation in a 5% CO₂ incubator at 37° C., the cells in the plates were loaded with 20 μl/well of a dye loading solution containing the acetomethoxy ester of the thallium-sensitive fluorescent dye BTC, BTC-AM (2 μM) and pluronic acid (0.02% w/v) in chloride free assay buffer. Chloride free assay buffer was composed of the following: sodium gluconate, 140 mM; potassium gluconate, 2.5 mM; hemi-calcium gluconate, 6 mM; hemi-magnesium gluconate, 2 mM; glucose, 5 mM; HEPES (pH 7.3), 10 mM.

Following incubation in the dye loading solution for from 45-90 min at room temperature, the dye loading solution was removed by aspiration and replaced with 40 μl/well of chloride free assay buffer.

Prior to addition to cell plates, test compound and standard compounds were dissolved in DMSO to 3 mM concentration. Compounds were then diluted from the 3 mM stock to 100-fold over the final assay concentration in DMSO. Finally, compounds in DMSO were diluted from 100-fold over the final assay concentration to 5-fold over the final assay concentration in chloride free assay buffer.

Ten μl/well of compounds at 5-fold over the final assay concentration were then added to the cell plates. This represents a 1:5 dilution, yielding the final test concentration. The wells used for test compounds were A1-P20. Wells A21-P22 contained a standard ‘blocker’ and a fully efficacious concentration (positive control). Wells A23-P24 contained chloride free assay buffer containing 1% DMSO (negative control).

Following addition of test compounds, the plates were loaded onto the Molecular Devices FLIPR. The 488 nm line of the argon laser was used to excite the BTC and the emission filter was a 540(±30) nm. Images were collected at 1 Hz. Ten seconds of baseline were collected and then the FLIPR was used to add 13 μl/well of a stimulus buffer composed of Tl₂SO₄, 25 mM; sodium gluconate, 30 mM; potassium sulfate, 50 mM; hemi-calcium gluconate, 6 mM; hemi-magnesium gluconate, 2 mM; glucose, 5 mM; HEPES (pH 7.3), 10 mM in chloride free assay buffer. Images were collected for an additional 60 seconds.

For data analysis, the amplitude of the average of the negative controls was subtracted from all wells. The amplitudes of the test compounds were then compared to the value of four standard deviations of the negative control wells. The lowest concentration of a test compound sufficient to generate a signal amplitude greater than or equal to four standard deviations from the amplitude of the negative controls was defined as the minimal active concentration.

For generating IC₅₀ values, compounds were serially diluted in 1:3 volume increments to produce a 10 point concentration series. IC₅₀ values were calculated by fitting the resulting amplitudes to a single-site logistic equation. IC₅₀ was defined as the concentration of test compound required to yield 50% of the response of the positive control.

The biological activity of several Formula I compounds are listed in Tables 1-3.

KCNQ Patch-clamp. Frog oocytes were surgically harvested from mature Xenopus laevis that had been anesthetized with 0.15% 3-aminobenzoic acid ethyl ester (tricaine). Only late stage V and VI oocytes were selected for cRNA injection, and the overlying follicle cell layers were enzymatically removed. Each oocyte was injected with approximately 60 ng of the mKCNQ2 cRNA. Following injection, oocytes were maintained at 17° C. in ND96 medium consisting of (in mM): NaCl, 90; KCl, 1.0; CaCl₂, 1.0; MgCl₂, 1.0; HEPES, 5.0; (pH 7.5) and supplemented with heat-inactivated horse serum (5%) and penicillin/streptomycin (5%).

Two-electrode voltage clamp techniques were used to record membrane currents; recording commenced 3-7 days following cRNA injection (Gribkoff, V. K., et al., Mol. Pharmacol. 1996, 50(1), 206-217). For recording and compound application, oocytes were placed in a recording chamber and incubated in Modified Barth's Solution (MBS) consisting of (in mM): NaCl, 88; NaHCO₃, 2.4; KCI, 1.0; HEPES, 10; MgSO₄, 0.82; Ca(NO₃)₂, 0.33; CaCl₂, 0.41; (pH 7.5). Voltage-clamp protocols consisted of a series of 4 second duration depolarizing voltage steps from a holding potential of −90 mV to a maximal potential of +40 mV in 10 mV intervals. A family of outward currents was generated under control conditions for comparison with currents elicited in the presence of an experimental compound. Control or drug solutions were continually introduced into the recording chamber using a gravity-flow system with an in-line electronic valve array. A minimum of 5 oocytes was used for each drug concentration; drug concentrations ranged from 0.001 μM to 10 μM. During a single experiment, an oocyte was exposed to as many as three drug concentrations sequentially administered for 5 minutes each. All experiments ended with a 5 minute application of TEA (5 mM), a non-selective, but effective blocker of KCNQ channels. Typically, 5 mM TEA produced a maximal blockade of outward current when measured at the −40 mV membrane voltage (94.6±0.5% inhibition, n=112). In this manner, all drug effects could be presented as a percentage of TEA blockade, controlling for the variable levels of channel expression from oocyte to oocyte. Table 1 discloses data for representative examples. Data are expressed as percent inhibition relative to TEA blockade at a membrane voltage of −40 mV: A>50% TEA blockage at 100 nM, B>50% TEA blockage at 1 μM, C<50% TEA blockage at 1.0 μM. TABLE 1 Percent TEA Example blockage 16 A 138 B 181 A 263 A 299 B A > 50% TEA blockage at 100 nM, B > 50% TEA blockage at 1 μM, C < 50% TEA blockage at 1.0 μM.
